of what is now US 9 in New York was assigned an unsigned legislative route designation by the New York State Legislature in 1908. Route 2 joined modern US 9 at Archville (north of Tarrytown) and followed it north to Croton-on-Hudson, where it turned off to the northeast on modern NY 129. The legislative route rejoined what is now US 9 at Peekskill and remained on it to Valatie, where it met Route 1. Route 2 ended here while Route 1 continued north to Albany on current US 9. From Albany to Clifton Park and from South Glens Falls to Riparius, modern US 9 was part of Route 25. At Riparius, Route 25 met Route 22, which utilized what is now US 9 from Riparius to Elizabethtown and from Keeseville to the town of Champlain. While modern US 9 travels directly from Elizabethtown to Keeseville and bypasses Rouses Point to the west, Route 25 used current NY 9N between Elizabethtown and Keeseville and served Rouses Point via modern NY 9B. Routes 2 and 25 were realigned slightly on March 1, 1921, to utilize the modern US 9 corridor from Croton-on-Hudson to Peekskill and from Saratoga Springs to South Glens Falls, respectively. When the first set of posted routes in New York were assigned in 1924, the general routing of modern US 9 was designated as New York State Route 6, which went from the New York City line at Yonkers north to the Canadian border near Rouses Point. From New York City, NY 6 followed current US 9 north to Tarrytown, where it joined legislative Route 2 and continued north through Valatie to Albany via legislative Routes 1 and 2. North of Albany, NY 6 served Cohoes, Mechanicville, and Round Lake via modern NY 32 and NY 67. At Round Lake, NY 6 rejoined the path of current US 9 and headed north to Saratoga Springs. Past Saratoga Springs, NY 6 continued to Rouses Point on legislative Routes 22 and 25. NY 6 had two spur routes: NY 6A in Westchester County and NY 6B in Rensselaer and Saratoga counties. Designation In the original 1925 plan for the U.S. Highway System, US 9 was designated along the west bank of the Hudson River from the New Jersey line to Albany, utilizing then-NY 10. North of Albany, US 9 mostly followed NY 6 to Canada. The lone deviation was from Elizabethtown
